WebSite Not Loading Correctly in Internet Explorer but ok in Firefox

I downloaded a theme called Zodiac Emporium. I really like the theme and it is supposed to show new posts on the homepage. The theme works correctly in Firefox but when I load the page in Internet Explorer the posts are all the way down at the bottom of the page and the place where they should have been has been replaced with white space.
The url for the site is https://www.newsblogrc.com

Pls can someone help me urgently, i really don’t want to have to change this theme.
I tried to contact the designer of the theme but got no reply.
